do your motor a favour, run 91, the 94 octane pump gas is oxiginated shit filled with ethanol up here and should not be run in any two stroke. I have more friends that blew up sled motors on that crap ..... its like leaning up a few jet sizes.
at 90 psi - you sure don't need 94 oct. You could run 87, but 91 is fine too. You could actually be causing some problems for yourself.
Tom's right, i tried to run 89 just to be safe , but I ran 87 alot without issue. With that compression you are making more power with the lower octane I think.
